"Arnaud is a complete player and able to adapt to all playing styles. He can play on any line, has a very good shot and imposes himself physically," Eric Castonguay, assistant coach of HC Sierre, said.
Arnaud Riat is already familiar with the organization. He played for them via B-license while he was still part of Genève-Servette HC and signed a full contract with them for the 2022-23 season. Last season, he recorded seven goals and eight assists in 45 regular-season games for HCV Martigny.
